127.0.0.1 ;-) The problem in this case is that for backwards-compatibility, the resolver library will return IPv4 address, unless (on OpenBSD) you use gethostbyname2(...,AF_INET6), and I don't think Perl exposes that stuff yet. > > The following patch (short of being to detect at configure time the > > IPv4/6 status of the box) hard-codes all the listening IP addresses to > > 127.0.0.1, effectively ensuring all the test suite runs under vanilla- > > IPv4. > > > > Ideally, I'd like to figure out a way to detect things correctly, and > > pick between 127.0.0.1 and ::1 accordingly. > > What happens if localhost != 127.0.0.1?

The availability of IPv6 on that box 2. Wether httpd was compiled with --enable-v4-mapped or not (or what it defaulted to) And once we can figure that out, then can we make a correct decision as to what to bind to. But, AFAIK, 127.0.0.1 (or ::1) _must_ be the a loopback address, isn't it ? > __________________________________________________________________ > Stas Bekman JAm_pH ------> Just Another mod_perl Hacker > http://stason.org/ mod_perl Guide ---> http://perl.apache.org > mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com > http://modperlbook.org http://apache.org http://ticketmaster.com
